Problems solved by technology

During the process from gas generation to fire extinguishing, if the particle size of the solid particles is too large, the gas will not be able to bear the load, and the particles will settle quickly, which will not achieve the effect of completely extinguishing the fire; but if the particles are too small, they will be easily absorbed by the airflow. Driven, it may be far away from the fire point or the fire source, and it will also not achieve the fire extinguishing effect of the project
In terms of research on the amount of solid particles, if the ratio of various elements in the formulation of the agent is unreasonable, the amount of gas will be small and the amount of solid particles will be too much, and it will also not be able to play an effective fire extinguishing role.

Embodiment 1

[0025] Embodiment 1: hot aerosol fire extinguishing agent, the fire extinguishing agent adopts 40 parts of oxidizing agent, 50 parts of reducing agent, 7 parts of performance modifier and 3 parts of adhesive in parts by mass. The oxidant can choose nitrates such as potassium nitrate and strontium nitrate and a small amount of carbonate. The oxidant is oxidizing, and it is reduced by itself. The nitrate is reduced in the chemical reaction to NO, NO 2 , N 2 . The pyrolysis products of solid particles exist in the form of steam or ions, and instantly adsorb and react with active groups such as H, OH, and O, thereby consuming fuel active groups and inhibiting the chain reaction of combustion. Among them, the metal oxide produced by the oxidation-reduction reaction reacts with the combustion substance carbon at high temperature, absorbs part of the heat of the combustion fire source, and reduces the flame temperature, so the combustion reaction is inhibited to a certain extent. C...

Embodiment 2

[0027] Embodiment 2: hot aerosol fire extinguishing agent, the fire extinguishing agent adopts 50 parts of oxidizing agent, 40 parts of reducing agent, 5 parts of performance modifier and 5 parts of adhesive in parts by mass. Adhesive can adopt resin type adhesive. The preparation process of the hot aerosol fire extinguishing agent can be made according to the conventional preparation process in the field, that is, the prepared oxidant, reducing agent, performance modifier and binder are mixed and stirred to form.

Embodiment 3

[0028] Embodiment 3: hot aerosol fire extinguishing agent, this fire extinguishing agent adopts 40~75 parts of oxidant, 15~50 parts of reductant, 1~7 parts of performance regulator and 1~5 parts of binding agent to make by mass parts; Parts include 10-15 parts of potassium nitrate, 20-25 parts of strontium nitrate, 3-5 parts of zinc nitrate, 3-5 parts of magnesium nitrate and 1-5 parts of calcium nitrate; 20-38 parts of amide; the performance modifier includes 1-2 parts of aluminum carbonate, 1-3 parts of magnesium carbonate and 1-3 parts of carbon powder.

Abstract

The invention discloses a hot aerosol fire extinguishing agent which is prepared by an oxidant, a reductant, a performance modifying agent, and an adhesive. The invention not only has good fire extinguishing effect, but also is energy-saving, environment-friendly, and low in cost; meanwhile, the invention does not cause corrosion or damage of equipment after utilization, and can effectively prevent secondary combustion of files and equipment.

Description

technical field [0001] The invention relates to a hot aerosol fire extinguishing agent, and relates to the technical field of gas fire extinguishing in fire protection technology. Background technique [0002] Aerosol-type fire extinguishing agent is a newly developed type of fire extinguishing agent in the field of fire extinguishing. It forms a large amount of aerosol gas after the fire extinguishing agent burns, and the aerosol gas completely floods the protected area to achieve the purpose of fire extinguishing. The Chinese patent with the publication number CN1166996A discloses an aerosol-forming pyrotechnic composition for extinguishing fire in a closed space, which comprises 67-72% potassium nitrate by weight, 8-12% phenolic resin, and the remaining amount of Dicyandiamide. This aerosol composition mainly has the following problems: [0003] 1. This aerosol composition is K-type hot aerosol fire extinguishing gas generating agent based on potassium nitrate as the ox...
